GROUND C AMP.

Application filed April 26, 1921. Serial No. 464,642.

To all whom it may concern:

Be it known that I, GnoiiGELIPsoHU'rz, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have 1nvented new. and useful Improvements in a Ground Clamp, of which the following is a specification. I

My invention relates to new and useful improvements in a ground clamp, and has for its object to improve the construction of such devices in order that the ordinary slot in the attaching plate or body may be eliminated and to provide means forreadily and securely fastening the body or. plate to the flexible band. J

Another object of the invention is to provide a plate having arcuate recesses or cavitie's formed therein for the reception of the arcuate ends of the arms formed with the tightening member whereby said tightening member will be caused to rotate for snugly drawing the band upon a pipe, rod or other suitable conductor. a

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may un' derstand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this applica tion. in which Fig. 1, is a plan view of my improved ground clamp showing it attached to a conductor, here illustrated as a pipe.

Fig. 2, is a side elevation thereof.

Fig. 3, isan end view.

Fig. 1, is a face view of the flexible band.

Fig. 5, is an edge view thereof.

Fig. 6, is an outer face view of the body or fulcrum plate.

Fig. 7, is an end view of the plate.

Fig. 8, is a section at the line 88 of Fig. 6. y

Fig. 9, is a side edge view of the plate.

Fig. 10, is a section at the line 101O of Fig. 6.

Fig. 11, is a side elevation of the tightening member.

Fig. 12, is an end or edge view thereof.

Fig. 13, is an inner plan view thereof.

f In carrying out my invention as here embodied, 2 represents the fulcrum plate or body having attaching lugs 3 formed in the region of each corner'of the plate or in other wordsone at each side adjacent each 1 end and these are adapted to be bent over and clenched upon-the'fiexible band 4: Of metal of any suitable conducting material so as to be securelyfastened to oneend of said band. On each side of the plate is formed a wing 5 located between the pair of attaching lugs on the same side and in thesewings are formed the arcuate recesses or cavities 6 by pressing the 'metal from said wings and the metal so pressedfrom I the wings forms a pair of parallel spaced projections 7 for a purpose to be hereinafter described, and this plate also has ahole 8 therethrough. I

"This fulcrum plate is attached to the flexible conductor band" adjacentthe end provided With'the loop- 9 for the reception of an electric conductor wire'and this band is therefore provided with a hole 10 adaptwall 13 with a hole 14 therethrough and a a pair of oppositely disposed arms 15 formed integral with the wall 13 and lying at right angles thereto and the outer ends of these arms are curved or arcuate in shape as at 16. The flexible conductor band l is placed about a suitable conductor such as a pipe 17 and the tightening member 12 is then placed in position on said band until the hole 14 therethrough aligns with one of the series of holes 11 after which a screw 18 is inserted through said hole and the holes 10 and 8 and a nut 19 threaded thereon. When the nut is in place upon the screw it is moved into a position between the proj'ections 7 as shown in Fig. 1 and the ends of the arms 15 are brought into alignment with the concave recesses 6 in the fulcrum plate then by turning the screw 18 the parts will be drawn toward one another. By rea- 15 engaging the arcuate recesses 6, thus tightening the band l firmly about the conductor or pipe 17.

From the foregoing description it will be v obvious that I have provided an exceedingly simple though strong and durable construction for a ground clamp that is relatively inexpensive in the cost of manufacture and which maybe placed upon a suitable conductor withoutthenecessity of threading the hand through any of the elements of the device and the fulcrum plate may be secured to said band by attaching lugs formed from its, own.material.- v I Of course I do not-wish to be limited to the exact detailsuo'f construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what claim as new and useful, is M In a device of the character described, afulcrum plate, a pair ofattaching lugs formedat'each side of said plate, a Wing betweeneach pair of attaching lugs, aroua te recesses formed in said Wing's, projecti o ns formed by the metal pressed from the wings to produce said recesses, a flexible band, a tightening member, and means for drawing the tightening member toward the fulcrum plate. p I

a device of the character described,

a fulcrum plate, .pair ofattaching lugs formed at each side of said plate, a Wing between each pair of attaching lugs, arouate recesses formed in said wings, pro ections formed by the metal pressed irom the wings to produce said recesses, a flexible band having a loop at one end and provided with a series of holes at its other end, said band having the fulcrumed plate secured thereto adjacent the looped end thereof, a tightening member consisting of a wall having an opening,therethrough, a pair of parallel arms projecting at right angles therefrom, the outer ends of said arms being arcuate in shape and the inner edges thereof approximately aligning'with the center pressed from the wings to produce said recesses. y

In testimony whereof, I have hereunto affixed my slgnature.

GEORGE LIPSCHUTZ.
